NUT-LOCK.

SPECIFICATION formingpart of Letters Patent No. 264,142, dated September12, 1882,

Application tiled August 8, 1882.

.To all 'whom it may concern:

Beit known that I, WALTER H. FABRA, of Mount Jackson, in the county ot'Shenandoah and State of Virginia, have invented certain new and usefulImprovements in Nut-Locks; and I do hereby declare that the following isa full, clear, and exact description ot' the in vention, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, which form apart ot' this specicatiou.

Figure l is a perspective view, showing a nut secured by my improvedlocking device.

Fig. 2 is a transverse sectional view oi' the same. Fig. 3 is aperspective viewof the locking-plate detached, and Fig. 4 is a sectionalview of the latter.

Corresponding parts in the several figures are denoted by like lettersofreference.

This inventionrelates to nut-locks; and it consists in certainimprovements in the construction of the same which will be hereinafterfully described, and particularly pointed ont in the claims.,

Referring to the drawings hereto annexed, A represents the outerbearing-plate, or part to be secured by the bolt B, which is ot' theordinary construction.

O is the lock-plate, which maybe an ordinary thin metallic plate, squareor of other suitable shape, and provided with a central opening, D, toreceive the bolt. The portion of plate C surrounding opening D isreenforced, as at E, and the said re-enforced portion is provided withdownward-projecting lugs or studs F, for the reception of which groovesor recesses G are provided in the face of the plate or part A. When,however, the said plate or part A is of Wood or other yielding materialthe reeesses'or grooves G need not be specially prepared, but may beformed (No model.)

ing the lugs F of plate C into plate A,or oausing them to lock or bindin the grooves G, thereby `preventing the lock-plate O from turning. Oneor more ot' the projecting corners of said plate are then turned upagainst the sides of the nut, which is thus locked securely andprevented from coming oli` by the rattling of machinery or from othercauses. The central portion ot' the locking-plate being re-enforced, asshown, gives great strength to-the locking studs or projections, Whilethe projecting corners, being comparatively'thin, may be easilyV bent tothe required position to lock the nut.

I claim and desire to secure by Letters Patent of the United Statcsl.The locking-plate O, having opening D, re-entorce E, and lugs or studsF, as described, for the purpose set forth.

2. The herein-described nut-lock, consisting of the plate A, havinggrooves G, bolt B, plate or Washer O, having re-entorceE, lugs or studsF, and opening D, and the nut H, the projecting corners ot' said plate Cheilig turned up against the sides of said nut, as set forth.

In testimony that I claim the foregoing as my own I have hereto aixed mysig-.nature in presence ot' two witnesses.

WALTER I-I. FABRA.
